Description

Component mounting device and carriage

Technical Field

The present invention relates to a component mounting device and a carriage for taking out a component from a carrier tape and mounting the component on a substrate.

Background

Conventionally, a component mounting device for mounting a component on a substrate is known. The component mounting device includes a substrate holding unit that holds a substrate, and a working head that takes out a component from a component supply unit and mounts the component on the substrate. As a component supply unit that supplies components in a component supply section, a tape feeder that uses a carrier tape in which a plurality of components are enclosed in a state of being aligned in a row is often used.

A component mounting device using a tape feeder as a component supply unit includes: a feeder base portion that holds a plurality of component supply units in an aligned manner; and a carrier tape cutting device for cutting the carrier tape from which the component is taken out by the operation head into a short strip shape. Since the carrier tape discharged from the component supply unit needs to be reliably introduced into the carrier tape cutting device, there are many cases in which: the carrier tape cutting device and the feeder base are provided in a group on the base side as described in, for example, japanese patent laid-open No. 2018-13308, or are provided in a group on a carriage mounted on a base as described in, for example, japanese patent laid-open No. 2009-64929. Since the carriage is detachably attached to the base and includes the feeder base portion, the carriage can be attached to the base in a state where the plurality of component supply units are mounted on the feeder base portion in a line, and thus the plurality of component supply units can be collectively attached to the base.

In the type disclosed in japanese patent application laid-open No. 2018-13308, in which a feeder base portion and a carrier tape cutting device are provided in a group on a base, the carrier tape cutting device is provided only one with respect to the base, and therefore, the maintenance work thereof is easy, but a plurality of component supply units cannot be collectively replaced. On the other hand, in the type disclosed in japanese patent application laid-open No. 2009-64929 in which the feeder base portion and the carrier tape cutting device are provided in a group on the carriage, the mounting work of the component supply unit is easy because a plurality of component supply units can be collectively replaced, but since the carrier tape cutting device is provided on each carriage, there is a difficulty that the maintenance work takes much time.

Disclosure of Invention

The component mounting device of the present invention includes: a component mounting section having: a base station; a substrate holding section provided on the base and holding the substrate; a work head for taking out the component from the carrier tape and mounting the component on the substrate held by the substrate holding portion; and a carrier tape cutting device for cutting the carrier tape from which the component is taken out; a carriage that is detachable from the base and has a feeder base portion that arranges and holds a plurality of component supply units that feed the carrier tape to a component pickup position where component pickup is performed by the work head; and a nullifying mechanism that disables the carrier tape cutting device from operating in a state where the carriage is separated from the base.

The carriage of the present invention is attachable to and detachable from a component mounting portion, the component mounting portion including: a base station; a substrate holding section provided on the base and holding the substrate; a work head for taking out the component from the carrier tape and mounting the component on the substrate held by the substrate holding portion; and a carrier tape cutting device for cutting the carrier tape from which the component is taken out by moving a cutter by a cutting operation of an actuator operated by energy transmitted through an energy transmission path, the carrier tape cutting device comprising: a feeder base part that arranges and holds a plurality of component supply units that feed the carrier tape to a component pickup position where component pickup is performed by the work head; and a midway portion of the energy transmission path, which is separated when the trolley is separated from the base, and the energy transmission path is disconnected.

According to the present invention, the safety of the operator with respect to the carrier tape cutting device can be ensured even in a state where the carriage is separated from the base.

In fig. 1 and 2, the component camera 15 is provided on the base 11 so that the imaging field of view is directed upward. When the work head 14 moves upward of the substrate KB in a state where the component is sucked by the suction nozzle 14N, the component camera 15 photographs the component from below and recognizes the component.

In fig. 2, the carrier tape cutting device 16 is provided at a position facing the component supply unit 1B of the base 11. The carrier tape cutting device 16 cuts the carrier tape CT (carrier tape CT after the work head 14 takes out the components) discharged from the component supply unit 22 into a short strip shape.

The component mounting device 1 having such a configuration is characterized by a configuration of the carrier tape cutting device 16 including the component supply unit 1B and the base 11 provided in the component mounting unit 1A in the present embodiment, and the following description will be given.

Fig. 9 is a cross-sectional side view of a component mounting unit 1A provided in the component mounting device 1 according to the embodiment of the present invention. In fig. 1 and 2, a pair of right and left protruding portions 11H are provided at both ends of the base 11 in the Y direction. The left and right projecting portions 11H project outward in the Y direction and face each other with a space in the X direction. A rear wall 11W of the base 11 extending along the XZ plane is provided at a root portion of the right and left extension portions 11H, and a front wall 11J (see fig. 9) extending along the XZ plane is disposed in front of the rear wall 11W so as to face the rear wall 11W in the Y direction. A space surrounded by the left and right projecting portions 11H and the rear wall 11W of the base 11 serves as a carriage assembly table 11S on which the carriages 21 of the component supply portion 1B are assembled.

The component supply unit 1B is mounted on a carriage mounting table 11S (fig. 1 and 2) at each of both ends of the base 11 in the Y direction. As shown in fig. 2 and 3, the carriage 21 includes a carriage base 31 and a feeder base portion 32. The carriage base 31 includes a plurality of casters 31C at the bottom thereof, and is capable of traveling on the floor surface. The operator can load and unload the carriage 21 to and from the base 11 by manually moving the carriage 21. A box-shaped scrap receiving portion 31T is provided at the bottom of the carriage base 31. The short strip-shaped carrier tape CT (chips) cut by the carrier tape cutting device 16 falls to the chip receiving portion 31T and is collected and recovered.

In fig. 2, a pair of left and right carriage guides 11G are provided on the lower portion on the inner surface (two surfaces facing each other in the X direction) side of the left and right extension portions 11H. The left and right carriage guides 11G are provided with a plurality of guide rollers 11R, respectively. The carriage guide portion 11G guides the carriage 21 approaching the base 11 by the plurality of guide rollers 11R when the carriage 21 is mounted on (inserted into) the carriage mounting table 11S. Thereby, the carriage 21 is smoothly guided into the carriage assembly table 11S.

In this way, the base 11 provided in the component mounting section 1A has the following structure: the vehicle has a pair of right and left projecting portions 11H projecting toward the side (front) of the carriage 21, and carriage guide portions 11G for guiding the carriage 21 approaching the base 11 are provided in the right and left projecting portions 11H.

In fig. 3, a guide column 33 is provided on the upper portion of the carriage base 31 so as to extend in the Z direction. The bottom 34 of the feeder base portion 32 is provided to the upper end portion of the guide column 33.

A support portion 35 is provided on the upper surface of the bottom portion 34 so as to extend upward, and a unit mounting portion 36 is attached to the upper end of the support portion 35.

The unit mounting portion 36 is mounted with a plurality of component supply units 22 (fig. 1) arranged in the X direction. The guide column 33 is slidable in the vertical direction, and therefore, the feeder base portion 32 can be raised and lowered with respect to the carriage base 31. A tape discharge guide 37 (fig. 3) is provided at the rear of the unit mounting portion 36 so as to extend downward.

In fig. 3, a reel RL is held by the carriage base 31. The carrier tape CT is wound around the reel RL. Each of the plurality of component supply units 22 mounted on the feeder base part 32 draws the carrier tape CT from the corresponding reel RL and feeds the leading part of the carrier tape CT backward (the component mounting part 1A side), thereby supplying the components to the component pickup position 22K. After the components are supplied to the component pickup position 22K (i.e., after the components are picked up by the work head 14), the carrier tape CT is discharged from the rear of the component supply unit 22 and guided downward by the tape discharge guide 37.

In this way, in the present embodiment, the feeder base part 32 is provided with the tape discharge guide 37 for guiding the carrier tape CT discharged from the component supply unit 22 downward.

Fig. 6 is a plan view of a component mounting unit 1A provided in the component mounting device 1 according to the embodiment of the present invention. Fig. 7 is a sectional view of the moving part 39 provided in the component mounting part 1A of the component mounting device 1 according to the embodiment of the present invention. In fig. 5, 6, and 7 (fig. 7 isbase:Sub>A cross-sectional view taken along linebase:Sub>A-base:Sub>A of fig. 5), the moving unit 39 includesbase:Sub>A pair of left and right front plates 41,base:Sub>A back plate 42,base:Sub>A pair of left and right side plates 43, andbase:Sub>A bottom plate 44. The left and right front plates 41 are each formed of a plate-like member extending along the XZ plane, and are arranged in the X direction at predetermined intervals. The back plate 42 is a plate-like member extending along the XZ plane and is positioned behind the left and right front plates 41.

In fig. 5, 6, and 7, the left and right side plates 43 are each formed of a plate-like member extending along the YZ plane. Ends in the width direction (X direction) of the left and right front plates 41 and ends in the width direction of the back plate 42 are joined to the left and right side plates 43. The front end portions of the left and right side plates 43 are positioned forward of the front plate 41.

The base plate 44 is formed of a plate-like member extending along the XY plane. The front end of the bottom plate 44 is joined to the lower portions of the left and right front plates 41, and the left and right end portions of the bottom plate 44 are joined to the left and right side plates 43. The bottom plate 44 is provided with a stopper insertion hole 44H penetrating in the thickness direction (Z direction).

The carrier tape cutting device 16 will be explained. As shown in fig. 5, 6, and 7, the carrier tape cutting device 16 is provided in a space surrounded by the left and right front plates 41, the back plate 42, the left and right side plates 43, and the bottom plate 44 of the moving section 39.

The carrier tape cutting device 16 includes a cutter 50 including a fixed blade 51 and a movable blade 52, and a cutter driving cylinder 53 that drives the cutter 50 (specifically, the movable blade 52). As shown in fig. 5 and 6, the fixed blade 51 and the movable blade 52 each have a shape extending in the X direction in a horizontal posture. The fixed blade 51 has an edge (fixed blade edge 51E) facing forward, and the movable blade 52 has an edge (movable blade edge 52E) facing backward.

In fig. 7, a pair of right and left rails 54 projecting upward and extending in the Y direction are provided on the upper surface of the bottom plate 44. A slider 55 is engaged with an upper edge side of each rail 54, and the slider 55 is slidable in the Y direction along the rail 54. A plate-shaped moving blade attachment portion 56 extending in the X direction in a horizontal posture is attached to the upper surface of the left and right sliders 55.

In fig. 5 and 6, the tool driving cylinders 53 are provided one on each of the left and right front plates 41. The left and right tool driving cylinders 53 are constituted by air cylinders, and the output shafts 53J are directed rearward (fig. 7). The output shaft 53J of each tool driving cylinder 53 penetrates the front plate 41 rearward, and its front end portion is coupled to the lower surface side of the moving blade attachment portion 56 via a block-shaped coupling portion 57 (fig. 5 and 6).

In fig. 7, a fixed blade 51 is attached to the upper end of the back plate 42. The movable blade 52 is attached to the upper surface of the movable blade attachment portion 56, and is supported by the left and right rails 54 via the movable blade attachment portion 56 and the slider 55 so as to be movable in the Y direction. As described above, since the movable blade attachment portion 56 is coupled to the output shaft 53J of the left and right tool driving cylinders 53 via the left and right coupling portions 57, the movable blade 52 can be moved in the Y direction by the left and right tool driving cylinders 53.

Fig. 8A and 8B are cross-sectional views of the moving portion 39 provided in the component mounting portion 1A of the component mounting device 1 according to the embodiment of the present invention. When the left and right tool driving cylinders 53 advance the output shaft 53J, the movable blade 52 moves in a direction (rearward) approaching the fixed blade 51 (fig. 8A → 8B). When the left and right cutter driving cylinders 53 retract the output shaft 53J, the movable blade 52 moves in a direction (forward) away from the fixed blade 51 (fig. 8B → 8A).

In fig. 7, a flat plate-shaped fixed safety cover 58 extending in the X direction in a horizontal posture is provided in front of the fixed blade 51. The fixed safety cap 58 is provided at a position covering a part of the moving range of the moving blade 52 in the Y direction from above.

In fig. 7, the lower end portion of the tape discharge guide 37 of the feeder base portion 32 is located above a space sandwiched by the fixed blade 51 and the fixed safety cap 58. Therefore, a space is formed between the fixed blade 51 and the fixed safety cover 58 to move the carrier tape CT discharged from the component supply unit 22 from the top to the bottom. This space functions as an inlet for the carrier tape CT to the cutter 50, and is hereinafter referred to as a "carrier tape inlet 59".

In fig. 7, 8A, and 8B, the fixed blade 51 has its edge (fixed blade edge 51E) positioned in the carrier tape introduction port 59. That is, the fixed blade 51 is in a state of protruding in the horizontal direction with respect to a space (carrier tape introduction port 59) in which the carrier tape CT moves from the top to the bottom. On the other hand, when the moving blade 52 moves backward and approaches the fixed blade 51, the edge (moving blade edge 52E) thereof is positioned in the tape introduction port 59 (fig. 8B).

Fig. 5 and 8A show a state in which the tool driving cylinder 53 operates the output shaft 53J to retract the movable blade 52 to the maximum. Hereinafter, the position of the moving blade 52 is referred to as a "most retreated position". In a state where the moving blade 52 is located at the most retreated position, the moving blade edge 52E is located below the fixed safety cap 58.

Fig. 6 and 8B show a state in which the cutter driving cylinder 53 operates the output shaft 53J to advance the movable blade 52 to the maximum. Hereinafter, the position of the moving blade 52 is referred to as a "most advanced position". In a state where the moving blade 52 is located at the most advanced position, the moving blade edge 52E advances to below the fixed blade 51.

Fig. 10 is a cross-sectional side view of a component mounting unit 1A provided in the component mounting device 1 according to the embodiment of the present invention. In fig. 7, a plate-shaped cutting guide 61 extending entirely along the XZ plane is provided on the rear side of the bottom plate 44. The space between the cutting guide 61 and the back plate 42 serves as a chip passage 62 extending in the Z direction, and a discharge port 63 is provided at a lower portion of the chip passage 62. As shown in fig. 9 and 10, a discharge duct 11D fixed to the rear wall 11W and the front wall 11J is provided below the discharge port 63. The chips discharged from the discharge port 63 are sent to the chip receiver 31T through the discharge duct 11D.

When the moving blade 52 moves from the most retracted position to the most advanced position, the moving blade edge 52E crosses the cutting position 50P (fig. 7 and 8A) located between the carrier tape introduction port 59 and the discharge port 63 (more specifically, above the fixed blade edge 51E). At this time, if the object to be cut is present at the cutting position 50P, the movable blade cuts the object to be cut by the relative movement of the movable blade edge 52E and the fixed blade edge 51E.

Hereinafter, the operation of cutting the object to be cut by the movement of the moving blade 52 by the cutter 50 in this manner will be referred to as a "cutting operation". In the present embodiment, the "object to be cut" is the carrier tape CT introduced from the component supply unit 22 into the carrier tape introduction port 59 through the tape discharge guide 37 (i.e., after component removal).

After the cutter 50 performs the cutting operation and the moving blade 52 is positioned at the most advanced position, the left and right cutter cylinders 53 retract the output shaft 53J and return the moving blade 52 to the most advanced position (fig. 6 → 5 and 8B → 8A). The cutter driving cylinder 53 always positions the movable blade 52 at the most retracted position in a state where the carriage 21 is separated from the base 11.

As described above, in the present embodiment, the carrier tape cutting device 16 (cutter 50) is provided near the carrier tape introduction port 59. The cutter 50 (moving blade 52) is moved by the left and right cutter driving cylinders 53 as a cutter driving unit, and the carrier tape CT introduced from the carrier tape introduction port 59 is cut at the cutting position 50P between the carrier tape introduction port 59 and the discharge port 63.

Here, as shown in fig. 7, 8A, and 8B, since the tape discharge guide 37 of the feeder base part 32 is positioned directly above the carrier tape introduction port 59, the carrier tape CT discharged from the component supply unit 22 is smoothly guided to the cutting position 50P. Further, as described above, since the cutter 50 of the carrier tape cutting device 16 is provided in the vicinity of the carrier tape inlet 59, the length of the tip portion of the carrier tape CT cut by the cutter 50 protruding downward from the feeder base portion 32 can be shortened. Therefore, the leading end portion of the carrier tape CT does not become an obstacle when the carriage 21 is transported and mounted on the other component mounting apparatus 1.

The carrier tape CT (chips of the carrier tape CT) cut into a short strip shape by the cutter 50 falls through the chip passage 62, and is discharged from the discharge port 63 to the chip receptacle 31T through the discharge duct 11D. As described above, the component mounting device 1 of the present embodiment includes the discharge port 63 for discharging the cut carrier tape CT and the discharge duct 11D.

In fig. 7, a carriage stopper 64 (see also fig. 5 and 6) is provided at the rear portion of each of the left and right side plates 43. The left and right carriage stoppers 64 extend upward, respectively, and abut against a rear end portion 34T (fig. 3) of the bottom portion 34 of the feeder base portion 32 of the carriage 21 when the carriage 21 is inserted into the carriage assembly table 11S of the base 11 as described later.

In fig. 9 and 10, three guide rollers 70 are provided at three locations on the outer surface side of each of the left and right side plates 43 (see also fig. 5 and 6). The three guide rollers 70 are constituted by a rear upper roller 70a, a rear lower roller 70b, and a front roller 70 c. The rear upper roller 70a is positioned above the rear portion of the side plate 43, and the rear lower roller 70b is positioned below the rear upper roller 70 a. The front roller 70c is positioned in front of the upper roller 70 a.

Fig. 11 is a side view of the protruding portion 11H and the guide plate 11P provided in the component mounting unit 1A of the component mounting device 1 according to the embodiment of the present invention. Fig. 12A, 12B, and 12C are side views of the guide plate 11P provided in the component mounting unit 1A of the component mounting device 1 according to the embodiment of the present invention. In fig. 4, 9, and 10, guide plates 11P are provided on the inner surfaces of the left and right projecting portions 11H of the base 11. The left and right guide plates 11P are each formed of a plate-like member extending along the YZ plane. As shown in fig. 11, 12A, 12B, and 12C, the guide plate 11P includes a rear upper guide groove 71 provided corresponding to the rear upper roller 70a included in the moving portion 39 and a rear lower guide groove 72 provided corresponding to the rear lower roller 70B.

In fig. 11, the rear upper guide groove 71 includes a first vertical region 71a extending in the Z direction in front of the rear reference piece 73 having a substantially rectangular shape provided on the guide plate 11P, and a first horizontal region 71b extending rearward (above the rear reference piece 73) from an upper portion of the first vertical region 71 a. The rear upper guide groove 71 is positioned to guide the movement of the rear upper roller 70a on the inner side thereof in the direction of the YZ plane. That is, the upper rear roller 70a is guided in the vertical direction in the first vertical region 71a, and the upper rear roller 70a is guided in the horizontal direction (the direction along the Y axis) in the first horizontal region 71b. A longitudinal surface KY1 on the rear side of the first lateral region 71b of the rear upper guide groove 71 restricts the moving range of the rear upper roller 70a in the direction along the Y axis. The lower edge of the first lateral region 71b, i.e., the upper surface KZ1 of the rear reference piece 73 guides the movement of the rear upper roller 70a in the direction along the Y axis.

In fig. 11, the rear lower guide groove 72 has a second vertical region 72a extending in the Z direction and a second horizontal region 72b extending rearward from an upper portion of the second vertical region 72 a. The rear lower guide groove 72 is positionally guided in alignment with the movement of the rear lower roller 70b on the inner side thereof in the direction of the YZ plane. That is, the rear lower roller 70b is guided in the vertical direction in the first vertical region 72a, and the rear lower roller 70b is guided in the horizontal direction (the direction along the Y-axis) in the first horizontal region 72b.

In fig. 11, a front reference piece 74 is provided at the front end of the guide plate 11P. A vertical surface KY3 is formed at the rear upper side of the front reference piece 74 of the guide plate 11P. The front reference sheet 74 guides the movement of the front roller 70c in the vertical direction by its front surface 74a, and guides the movement in the horizontal direction (direction along the Y axis) by the upper surface KZ 3. The vertical plane KY3 restricts the moving range of the front roller 70c in the direction along the Y axis.

The moving portion 39 can be moved from the position shown in fig. 12A (referred to as a "first position") through the position shown in fig. 12B (referred to as an "intermediate position") to the position shown in fig. 12C (referred to as a "second position"). Conversely, the moving portion 39 may be moved from the second position to the first position through the intermediate position.

Here, in a state where the moving portion 39 is located at the first position, the rear upper roller 70a abuts against a lower edge of the first vertical region 71a of the rear upper guide groove 71, and the rear lower roller 70b abuts against a lower edge of the second vertical region 72a of the rear lower guide groove 72. The front roller 70c is positioned in front of the front reference plate 74 (fig. 12A). In the state where the moving portion 39 is located at the second position, the rear upper roller 70a is located in the first lateral region 71b of the rear upper guide groove 71 and abuts against the upper surface KZ1 of the rear side reference piece 73, and the front roller 70c abuts against the upper surface KZ3 of the front side reference piece 74. The rear lower roller 70b is located in a second lateral region 72b of the rear lower guide groove 72 (fig. 12C).

When the moving portion 39 moves from the first position to the second position, the moving portion 39 moves upward to reach the intermediate position, and then moves in the horizontal direction (rearward) to reach the second position. When the moving portion 39 moves from the second position to the first position, the moving portion 39 moves horizontally (forward) to reach the intermediate position, and then moves downward to reach the first position.

When the moving unit 39 moves between the first position and the second position as described above, the three guide rollers 70 included in the moving unit 39 are guided by the left and right guide plates 11P provided on the left and right projecting portions 11H of the base 11, and the rear reference piece 73 and the front reference piece 74 provided on the left and right guide plates 11P, respectively. That is, the left and right guide plates 11P and the rear reference piece 73 and the front reference piece 74 provided to the left and right guide plates 11P respectively serve as a moving part guide mechanism 75 (fig. 11) when the moving part 39 moves relative to the base 11.

As described above, the present embodiment has the following structure: the moving part driving mechanism 40 is provided between the pair of projecting parts 11H of the base 11, and a moving part guide mechanism 75 that guides the moving part 39 moved by the moving part driving mechanism 40 is provided in the pair of projecting parts 11H.

In fig. 5, 6, and 7, right and left projecting pieces 76 are provided on the back plate 42 of the moving portion 39 so as to project rearward. Drive rollers 77 driven about the X-direction as a rotation axis are attached to the respective front end portions of the left and right projecting pieces 76.

In fig. 9 and 10, the moving part driving mechanism 40 is configured to include an L-shaped metal fitting 81, a swinging member 82, a rod driving cylinder 83, a rod support 84, and a driving rod 85 on the left and right, respectively. The L-shaped fitting 81 is attached to a lower portion of the rear surface of the rear wall 11W of the base 11 and has a portion extending horizontally rearward. The swing member 82 has a distal end portion pivotally connected to a portion of the L-shaped fitting 81 extending horizontally rearward, and is swingable along the YZ plane. The rod driving cylinder 83 is attached to the swinging member 82 and located on the rear surface side of the rear wall 11W. The rod driving cylinder 83 is constituted by an air cylinder, and the operation rod 83R as an output shaft is directed upward.

In fig. 9 and 10, the lever support portion 84 is provided at a position above the L-shaped fitting 81 in the rear wall 11W. A drive lever 85 is pivoted to a front end portion of the lever support portion 84 by a pivot shaft 84J extending in the X direction. A rear end portion of the drive lever 85 is pivoted to an upper end portion of the operation rod 83R of the rod drive cylinder 83 by a coupling shaft 86 extending in the X direction. Therefore, when the rod driving cylinder 83 advances and retreats the operating rod 83R, the driving rod 85 swings about the pivot shaft 84J, and the tip end portion is lifted and lowered.

Specifically, when the rod cylinder 83 moves the operating rod 83R forward, the drive rod 85 swings about the pivot shaft 84J in the direction in which the distal end portion descends, and in a state in which the operating rod 83R has moved forward to the maximum, the drive rod 85 assumes a posture in which the distal end portion descends to the maximum (fig. 9). Further, the drive lever 85 is swung in a direction in which the distal end portion is lifted when the lever drive cylinder 83 retracts the operation lever 83R, and the drive lever 85 is in a posture in which the distal end portion is lifted to the maximum extent in a state in which the operation lever 83R is retracted to the maximum extent (fig. 10).

In fig. 9 and 10, an opening 11K penetrating in the thickness direction (Y direction) is provided in an intermediate portion of the rear wall 11W of the base 11. Therefore, the protruding piece 76 and the driven roller 77 provided in the moving portion 39 can move forward and backward toward the rear wall 11W through the opening 11K.

In fig. 9 and 10, the distal end portion of the drive lever 85 is formed in a fork shape. The front end portions (fork-shaped portions) of the left and right drive levers 85 are engaged with the left and right driven rollers 77 provided on the rear surface side of the moving section 39 from the rear (fig. 9).

Fig. 13A and 13B are cross-sectional side views of the moving portion 39 provided in the component mounting portion 1A of the component mounting device 1 according to the embodiment of the present invention. In a state where the carriage 21 is separated from the base 11 (a state where the carriage 21 is not inserted into the carriage assembly table 11S), the lever drive cylinder 83 advances the operation lever 83R to the maximum extent (fig. 9), and the drive lever 85 lowers the tip end portion to the maximum extent. In this state, the moving portion 39 is located at the first position (fig. 12A), and the moving portion 39 is located at a position close to the front wall 11J from behind (fig. 13A).

When the lever driving cylinder 83 moves the operating rod 83R backward from a state in which the operating rod 83R is maximally advanced, the driving rod 85 swings in a direction in which the front end portion is lifted. Thereby, the driven roller 77 engaged with the tip end portion (the fork-like portion) of the drive lever 85 is lifted by the drive lever 85, and the moving portion 39 is raised from the first position to reach the intermediate position (fig. 12A → fig. 12B).

When the lever driving cylinder 83 retreats the operating lever 83R further, the driving lever 85 raises the tip end portion further. Thereby, the moving portion 39 is pulled by the drive rod 85 and moved rearward from the intermediate position (fig. 12B → fig. 12C), and is held at the second position (fig. 12C) in a state where the operating rod 83R of the rod drive cylinder 83 is retracted to the maximum extent. The moving portion 39 held at the second position is located at a position close to the rear wall 11W from the front (fig. 10 and 13B).

As described above, the component mounting device 1 according to the present embodiment includes: a base 11 provided with a working head 14 for mounting the components supplied by the component supply unit 22 on the substrate KB; and a carriage 21 which has a feeder base part 32 holding the plurality of component supply units 22 in an aligned manner, and which is detachably attached to the base 11, wherein the base 11 is provided with: a moving section 39 in which the carrier tape cutting device 16 is built; and a moving section driving mechanism 40 that drives the moving section 39.

Fig. 14 is a diagram illustrating a power air transmission path provided in the component mounting apparatus 1 according to the embodiment of the present invention. Here, a transmission path of the power air for driving the actuator in the component mounting apparatus 1 will be described. Fig. 14 shows a power air transmission path in a state where the carriage 21 is attached to the base 11.

In fig. 14, a power air transmission pipe (referred to as "first power air transmission pipe DK 1") for supplying power air to the left and right tool cylinders 53 includes a first base-side pipe 91, a relay pipe 92, and a second base-side pipe 93, and the second base-side pipe 93 is connected to a power air supply unit DA via a valve device VL. The first base-side pipe 91 and the second base-side pipe 93 are pipes provided in the base 11, and the relay pipe 92 is a pipe provided in the carriage 21. The valve device VL is provided on the base 11, and is controlled to operate by a controller 11CT (fig. 2) provided in the base 11. The motive air supply unit DA is provided outside the component mounting device 1.

In fig. 14, the first base-side pipe 91 and the trunk pipe 92 of the first power air transmission pipe DK1 are connected by the connection of the first coupler socket 94a on the base 11 side and the first coupler plug 95a on the carriage 21 side, and the trunk pipe 92 and the first base-side pipe 91 are connected by the connection of the second coupler plug 95b on the carriage 21 side and the second coupler socket 94b on the base 11 side. That is, the first power air transmission pipe DK1 has the structure: the first base-side piping 91-the coupler (first coupler socket 94 a-first coupler plug 95 a) -the relay pipe 92-the coupler (second coupler plug 95 b-second coupler socket 94 b) -the second base-side piping 93.

In this way, in the present embodiment, the power air as energy is supplied to the blade driving cylinder 53 through the first power air transmission pipe DK1 configured as described above, and the blade 50 of the carrier tape cutting device 16 is operated. Here, the first power air transmission pipe DK1 serves as an energy transmission path for transmitting energy for driving the tool driving cylinder 53, which is an actuator provided on the base 11 side, from the base 11 side to the bogie 21 side.

In this way, in the first power air transmission pipe DK1 for supplying power air to the left and right tool drive cylinders 53, the middle portion TB constituted by the first coupling plug 95a, the relay pipe 92, and the second coupling plug 95b is disposed on the carriage 21 side (fig. 14). Therefore, in a state where the carriage 21 is not attached to the base 11, the middle portion TB is separated from the first power air transmission pipe DK1, and the first coupling plug 95a and the first coupling socket 94a and the second coupling plug 95b and the second coupling socket 94b are disconnected from each other, so that the tool driving cylinder 53 cannot be operated.

Therefore, in the present embodiment, the carriage 21 needs to be attached to the base 11 in advance in order to operate the tool driving cylinder 53. In other words, the cutter 50 of the carrier tape cutting device 16 is not driven in a state where the carriage 21 is separated from the base 11.

The above-described structure of "the intermediate portion TB provided on the carriage 21 side is separated from the first power air transmission pipe DK1 (the first power air transmission pipe DK1 is cut off) and the cutting operation by the carrier tape cutting device 16 is restricted in the state where the carriage 21 is separated from the base 11" functions as a nullification mechanism for disabling the carrier tape cutting device 16 in the state where the carriage 21 is separated from the base 11. The component mounting device 1 of the present embodiment includes such invalidation mechanism, so that even when the cutter 50 of the tape cutting device 16 is positioned within the reach of the hand of the operator in a state where the carriage 21 is separated from the base 11, the safety of the operator is ensured.

In fig. 14, a power air transmission pipe (referred to as a "second power air transmission pipe DK 2") that supplies power air to the component supply unit 22 mounted on the feeder base part 32 includes a pipe insertion port 101, a plurality of independent pipes 102, a manifold 103, a main pipe 104, and a third base-side pipe 105, and the third base-side pipe 105 is connected to the power air supply part DA via a valve device VL. The pipe insertion port 101, the plurality of independent pipes 102, the manifold 103, and the main pipe 104 are provided in the carriage 21, and the third base-side pipe 105 is provided in the base 11. The plurality of pipe insertion ports 101 provided in the carriage 21 are connected to pipe plugs 22a provided in the component supply unit 22 to receive the supply of the power air.

In fig. 14, a main pipe 104 and a third base side pipe 105 of the second power air transmission pipe DK2 are connected by connecting the third coupler plug 95c on the carriage 21 side to the third coupler socket 94c on the base 11 side. That is, the second power air transmission pipe DK2 has the structure: piping socket 101-a plurality of independent piping 102-manifold 103-main piping 104-couplings (third coupling plug 95 c-third coupling socket 94 c) -third base-side piping 105.

As described above, in the present embodiment, the component supply unit 22 is operated by supplying the power air as energy to the feeder base part 32 side through the second power air transmission pipe DK2 configured as described above. Here, the second power air transmission pipe DK2 serves as an energy transmission path for transmitting energy for driving the component supply unit 22, which is a device provided on the bogie 21 side.

In the present embodiment, one of the couplers (the third coupler plug 95 c) constituting the second power air transmission pipe DK2 is provided on the bogie 21 side, and the other coupler (the third coupler socket 94 c) is provided on the base 11 side (fig. 14). Therefore, the couplings are separated in a state where the carriage 21 is not attached to the base 11, and therefore even if the component supply unit 22 is mounted on the feeder base portion 32 of the carriage 21, the component supply unit 22 does not operate as long as the carriage 21 is not attached to the base 11.

In fig. 14, the power air transmission piping for supplying power air to the right and left rod drive cylinders 83 provided on the base 11 is constituted only by the fourth base-side piping 106 provided on the base 11 side. Therefore, even when the carriage 21 is not attached to the base 11, the power air can be supplied to the left and right rod cylinders 83, and the movement of the moving unit 39 between the first position and the second position by the left and right rod cylinders 83 can be performed regardless of whether or not the carriage 21 is attached to the base 11.

In fig. 10, 13A, and 13B, a safety stopper 11T is provided to extend upward above the front wall 11J constituting the moving portion 39. The safety stopper 11T passes through the stopper insertion hole 44H from below in a state where the carriage 21 is separated from the base 11 and the moving portion 39 is located at the first position (fig. 9 and 12A). As described above, while the movable blade 52 is located at the most retracted position in the state where the carriage 21 is separated from the base 11, the safety stopper 11T mechanically prevents the movable blade 52 from advancing toward the fixed blade 51 by locating the tip portion immediately behind the joint portion 57 connected to the movable blade 52 located at the most retracted position (fig. 13A). Hereinafter, the position at which the safety stopper 11T passes through the stopper insertion hole 44H from below and stops the movement of the moving blade 52 is referred to as a "stopping position".

As described above, in the state where the safety stopper 11T is located at the blocking position, the movement of the moving blade 52 is mechanically blocked. Therefore, even if the cutter driving cylinder 53 is out of order or has a control error while the safety stopper 11T is in the stopping position, the cutter 50 does not perform the cutting operation, and the safety of the operator is ensured. When the moving portion 39 is moved from the first position to the second position by the rod driving cylinder 83 after the carriage 21 is attached to the base 11 (fig. 12A → fig. 12B → fig. 12C), the safety stopper 11T is disengaged from the stopper insertion hole 44H (moved downward of the bottom plate 44 of the moving portion 39) in the process, and thus the movement-blocked state of the moving blade 52 is released (fig. 13B and fig. 10).

In this way, the structure of "the safety stopper 11T is located at the stopping position and the movement of the moving blade 52 is stopped in the state where the carriage 21 is separated from the base 11" functions as a disabling mechanism (referred to as a second disabling mechanism) that disables the carrier tape cutting device 16 in the state where the carriage 21 is separated from the base 11, similarly to the disabling mechanism (referred to as a first disabling mechanism) described above. The component mounting device 1 of the present embodiment includes such a second invalidation mechanism, and thereby, even when the cutter 50 that carries the tape cutting device 16 in a state where the carriage 21 is separated from the base 11 is located within the reach of the hand of the operator, the safety of the operator is ensured.

In fig. 7, 13A, and 13B, a movable safety cap 111 is provided in the chip passage 62 of the moving part 39. The movable safety cover 111 is a plate-like member extending along the XZ plane as a whole, and is disposed on the front surface side of the back plate 42. The movable safety cover 111 changes the position with respect to the fixed blade 51 in the state where the moving portion 39 is located at the first position and the second position.

Fig. 15 is a side view of a part of the component mounting unit 1A of the component mounting device 1 according to the embodiment of the present invention. Fig. 16 is a side view of a part of the component mounting unit 1A of the component mounting device 1 according to the embodiment of the present invention. That is, in a state where the carriage 21 is not mounted on the carriage mounting base 11S (the moving portion 39 is located at the first position), the movable safety cover 111 is located at a position (protection position) where its upper end portion is located in front of the fixed blade 51 and covers the fixed blade edge 51E (fig. 13A and 15). On the other hand, in a state where the carriage 21 is inserted into the base 11 (the moving portion 39 is located at the second position), the carriage is retracted from the protection position and located at a position (exposure position) where the fixed blade edge 51E is exposed (fig. 13B and 16). The movable safety cover 111 is in a posture along the front surface of the back plate 42 below the fixed blade 51 in a state of being located at the exposure position so as not to interfere with the movement of the carrier tape CT passing through the carrier tape introduction port 59 (fig. 13B).

Here, a mechanism for moving the movable safety cover 111 between the protection position and the exposure position will be described with reference to fig. 15 and 16. As shown in fig. 15 and 16, a plate-shaped guided portion 112 is provided at a lower portion of the movable safety cover 111 so as to extend rearward. The back plate 42 of the moving portion 39 is formed with a safety cover guide groove 113 extending in the vertical direction and having a lower end portion bent forward. The guided portion 112 is provided with two safety cover guide pins 114 arranged in the vertical direction. The two safety cover guide pins 114 are positioned in the safety cover guide grooves 113 and are movable along the safety cover guide grooves 113.

As shown in fig. 15 and 16, a guide groove 115 extending in the vertical direction is provided in the rear wall 11W of the carriage 21. A rod-shaped connecting rod 116 extending obliquely downward from the back plate 42 side toward the rear wall 11W side is disposed between the back plate 42 of the moving portion 39 and the rear wall 11W of the base 11. The front end (upper end) of the link lever 116 is pivoted to the upper safety cover guide pin 114 among the upper and lower safety cover guide pins 114. On the other hand, the rear end (lower end) of the link 116 is pivoted to a guide pin 117 provided in the guide groove 115 (and thus movable in the up-down direction along the guide groove 115).

As shown in fig. 15, in a state where the moving portion 39 is located at the first position and the entire moving portion 39 is located at a position close to the front wall 11J (fig. 9), the movable safety cover 111 is in a pushed-up posture (fig. 15) by the link lever 116 having the guide pin 117 on the lower end side located at the lower end of the guide groove 115. In the state where the movable safety cover 111 is in such a posture, both the upper and lower safety cover guide pins 114 are positioned at the intermediate portion (portion extending in the vertical direction) of the safety cover guide groove 113. In addition, the movable safety cover 111 is in a posture in which the upper end side is tilted forward due to the relationship with the mounting positions of the upper and lower safety cover guide pins 114 to the movable safety cover 111, and is positioned at a protection position covering the fixed blade edge 51E.

On the other hand, as shown in fig. 16, in a state where the moving portion 39 is located at the second position and the entire moving portion 39 is close to the rear wall 11W, the back plate 42 is moved upward from the state where the moving portion 39 is located at the first position. At this time, the upper and lower safety cover guide pins 114 are positioned at the lower portion in the safety cover guide groove 113 by the self weight of the movable safety cover 111 (fig. 16). In this state, due to the inclination of the lower portion of the safety cover guide groove 113 from the vertical direction and the relationship with the mounting positions of the upper and lower safety cover guide pins 114 with respect to the movable safety cover 111, the movable safety cover 111 is positioned below the fixed blade 51, is in a posture along the front surface of the back plate 42, and is positioned at an exposed position where the fixed blade edge 51E is exposed (fig. 16).

As described above, the component mounting device 1 according to the present embodiment includes: a moving part 39 provided on the base 11 in a vertically movable state; and a movable safety cover 111 whose position is changed by the moving part 39. The movable safety cover 111 is displaceable between a protection position covering one edge (fixed blade edge 51E) of the fixed blade 51 of the cutter 50 and an exposure position not covering the fixed blade edge 51E, is located at the protection position in a state where the carriage 21 is separated from the base 11, and is displaced from the protection position to the exposure position when the moving portion 39 is raised with respect to the base 11. In a state where the carriage 21 is separated from the base 11, the edge (fixed blade edge 51E) of the cutter 50 is protected by the movable safety cover 111, thereby achieving safety of the operator.

In fig. 13A and 13B, horizontal support surfaces 121 are formed at the middle portion and the front end portion in the Y direction of the upper surface of each of the left and right side plates 43. Each support surface 121 is provided with an engagement pin 122 (see also fig. 5 and 6) so as to protrude upward.

Fig. 17A and 17B are cross-sectional side views showing a part of the moving portion 39 provided in the component mounting portion 1A of the component mounting device 1 according to the embodiment of the present invention together with a part of the feeder base portion 32. Fig. 18A and 18B are plan views of the connection unit 130 provided in the component mounting unit 1A of the component mounting device 1 according to the embodiment of the present invention. In fig. 5 and 6, a connecting portion 130 is provided between the left and right front plates 41 of the moving portion 39. As shown in fig. 17A, 17B, 18A, and 18B, the connection portion 130 includes a base 131, left and right rail portions 132, a floating member 133, an electrical connector socket 134, the three coupling sockets 94 (the first coupling socket 94a, the second coupling socket 94B, and the third coupling socket 94 c), a shutter 136, and a shutter driving roller 137.

Fig. 19A and 19B are cross-sectional side views showing the engagement of the coupler plug and the coupler socket in the component mounting unit 1A of the component mounting device 1 according to the embodiment of the present invention. In fig. 17A, 17B, 18A, 18B, 19A, and 19B, the base 131 is a plate-shaped member extending along the XY plane, and is fixed to the bottom plate 44 of the moving portion 39. The left and right rail portions 132 are disposed on the left and right sides of the base 131, and are provided to extend in the Y direction.

In fig. 17A, 17B, 18A, 18B, 19A, and 19B, the floating member 133 is formed of a plate-like member extending along the XY plane. Four support columns 138 erected on the base 131 penetrate four corners of the floating member 133 in the thickness direction. Spring members 139 are inserted through the four support posts 138, and the four spring members 139 support four corners of the floating member 133 from below. In this way, the floating member 133 is elastically supported by the four spring members 139, and is in a so-called floating state.

In fig. 17A, 17B, and 18B, three coupler insertion holes 94 (a first coupler insertion hole 94a, a second coupler insertion hole 94B, and a third coupler insertion hole 94 c) on the moving portion 39 side (the base 11 side) are attached to the floating member 133 in a posture in which the openings thereof face upward. The three coupler sockets 94 are arranged in the X direction in the order of the first coupler socket 94a, the third coupler socket 94c, and the second coupler socket 94 b. A first base-side pipe 91 is connected to the first coupler socket 94a, and a second base-side pipe 93 is connected to the second coupler socket 94 b. A third base-side pipe 105 (fig. 19A and 19B) is connected to the third coupler socket 94 c.

In fig. 17A, 17B, and 18B, the electrical connector socket 134 is also attached to the floating member 133 in a posture in which the opening faces upward. The electric connector jack 134 is connected to the control unit 11CT and a power supply device (not shown) via a wire 140 (fig. 17A and 17B) for supplying power and transmitting signals.

In fig. 18A, 18B, 19A, and 19B, a positioning pin guide 141 is provided on both right and left sides of the floating member 133. Each of the positioning pin guides 141 is provided with a guide hole 142 formed to penetrate in the Z direction.

In fig. 18B, the shutter 136 includes: a shutter main body 136a formed of a plate-like member extending in the XY plane as a whole; and left and right leg portions 136b extending downward from both left and right end portions on the front end side of the shutter main body portion 136 a. The left and right leg portions 136b are slidable in the Y direction on the left and right rail portions 132, and the entire shutter 136 is movable in the Y direction with respect to the base 131.

The shutter 136 is moved in the Y direction to switch the position between the shielding position (fig. 17A and 18A) and the retracted position (fig. 17B and 18B). Here, the "shielded position" refers to a position where the three coupler insertion openings 94 and the electrical connector insertion opening 134 (and therefore the openings of these insertion openings) are covered from above by the shutter main body portion 136 a. The "retracted position" is a position retracted rearward from the shielding position to expose the three coupling insertion holes 94 and the electrical connector insertion hole 134.

In fig. 18A and 18B, the shutter driving roller 137 is provided on one outer surface side of the left and right leg portions 136B so as to be rotatable about an axis extending in the X direction. The other of the left and right leg portions 136b is provided with a shutter side pin 143 projecting and extending outward in the X direction, and a side surface of the pedestal 131 (a side surface on which the shutter side pin 143 is provided) is provided with a pedestal side pin 144 projecting and extending in the X direction. The shutter-side pin 143 and the pedestal-side pin 144 are arranged in line in the Y direction, and a shutter spring 145 made of a tension spring is attached between the shutter-side pin 143 and the pedestal-side pin 144.

In a state where no external force is applied to the shutter driving roller 137, the shutter 136 is pulled forward by the elastic force of the shutter spring 145 and is positioned at the shielding position (fig. 17A and 18A). On the other hand, when the shutter 136 is pushed rearward by the shutter driving roller 137 from the state of being located at the shielding position against the elastic force of the shutter spring 145, the shutter 136 moves rearward and is located at the retracted position (fig. 17B and 18B).

Fig. 20A and 20B are sectional side views showing the feeder base part 32 of the component supply part 1B of the component mounting device 1 according to the embodiment of the present invention together with the component supply unit 22. In fig. 17A, 17B, 20A, and 20B, four engagement pin insertion holes 151, which are opened downward, in front of, rear of, and in right and left of, a lower surface of the bottom portion 34 of the feeder base portion 32 are provided. In addition to the three coupling plugs 95 (the first coupling plug 95a, the second coupling plug 95B, and the third coupling plug 95 c), an electric connector plug 152, a shutter drive pin 153, and left and right positioning pins 154 are provided on the lower surface of the bottom portion 34 so as to extend downward (see also fig. 19A and 19B).

In fig. 19A and 19B, three coupling plugs 95 are arranged in the X direction in the order of the first coupling plug 95a, the third coupling plug 95c, and the second coupling plug 95B, and are positioned between the left and right positioning pins 154. A main pipe 104 is connected to the third coupler plug 95c, and the main pipe 104 extends on the upper surface side of the bottom portion 34. The relay pipe 92 connecting the first coupler plug 95a and the second coupler plug 95b is located on the upper surface side of the bottom portion 34.

In fig. 20A and 20B, the plurality of pipe insertion ports 101 described above are provided at the front end portion of the unit mounting portion 36 so as to open forward (toward the component supply unit 22). A wiring socket 161, which is a part of a circuit (electrical system circuit) for supplying power to the component supply unit 22 and transmitting a signal, is also provided at the front end of the unit mounting portion 36 so as to be open forward. The component supply unit 22 mounted on the unit mounting portion 36 is provided with a piping plug 22a for introducing motive air and a wiring plug 22b for supplying electricity, respectively, so as to protrude rearward (the bogie 21 side).

In fig. 20A and 20B, the manifold 103 and the relay board 162 constituting a part of the electric system circuit described above are provided in the support portion 35 of the feeder base portion 32. The manifold 103 is connected to the three connector plugs 95 via a main pipe 104, and is connected to a pipe insertion port 101 via an independent pipe 102. The relay board 162 is connected to the electrical connector plug 152 via a main cable 163, and is connected to the wiring socket 161 via an independent wiring 164.

Next, a procedure of attaching the carriage 21 to the base 11 will be described. When the carriage 21 is attached to the base 11, first, the component supply unit 22 is attached to the carriage 21 in a state separated from the base 11.

Fig. 21 is a side view showing a state in which the component supply unit 1B of the component mounting device 1 according to the embodiment of the present invention is separated from the component mounting unit 1A. As described above, in the state where the carriage 21 is separated from the base 11 (fig. 21), the rod cylinder 83 of the moving part driving mechanism 40 is in the state where the operating rod 83R is advanced to the maximum extent (fig. 9). In this state, the three coupler plugs 95 as the carriage-side couplers and the three coupler sockets 94 as the base-side couplers in the first power air transmission pipe DK1 and the second power air transmission pipe DK2 are separated (fig. 17A and 19A), and the electrical connector plug 152 as the carriage-side connector and the electrical connector socket 134 as the base-side connector are also separated. Therefore, the cutter cylinder 53 of the carrier tape cutting device 16 is not operated by the operation of the first deactivation mechanism, and the cutter 50 is in a state in which the cutting operation is disabled.

In a state where the carriage 21 is separated from the base 11 (fig. 21), the shutter 136 of the connection portion 130 is located at the shielding position. Therefore, the three coupler sockets 94 and the electrical connector socket 134 mounted on the floating member 133 and the left and right positioning pin guides 141 (left and right guide holes 142) are covered with the shutter 136 (fig. 17A and 18B).

In a state where the carriage 21 is separated from the base 11, the moving portion 39 is located at the first position (fig. 9 and 12A), and the safety stopper 11T is located at the blocking position (fig. 13A) through the stopper insertion hole 44H of the moving portion 39. Therefore, the moving blade 52 of the carrier tape cutting device 16 cannot move toward the fixed blade 51 due to the operation of the second invalidation mechanism, and the cutter 50 is in a state in which the cutting operation is disabled. The movable safety cover 111 covers the fixed blade edge 51E (fig. 13A and 15).

When the operator mounts the component supply unit 22 on the carriage 21, the operator inserts the component supply unit 22 into the unit fitting portion 36 of the feeder base portion 32 from the rear in the horizontal direction (Y direction) (fig. 20A → fig. 20B). Thereby, the piping plug 22a on the component supply unit 22 side is fitted to the piping insertion opening 101 on the feeder base part 32 side from the front, and the wiring plug 22B on the component supply unit 22 side is fitted to the wiring insertion opening 161 on the feeder base part 32 side from the front (fig. 20B).

Fig. 22 is a side view showing the component mounting unit 1A and the component supply unit 1B of the component mounting device 1 according to the embodiment of the present invention. After mounting the required number of component supply units 22 on the carriage 21, the operator mounts the carriage 21 on the base 11. In contrast, first, the operator inserts the carriage 21 to which the component supply unit 22 is attached into the carriage assembly table 11S of the base 11 (fig. 21 → 22). At this time, the carriage base 31 is guided by the carriage guide portions 11G (guide rollers 11R) provided in the left and right projecting portions 11H of the base 11, and thus smoothly enters the carriage assembly 11S.

When the carriage 21 is inserted into the carriage assembly table 11S, the rear end portion 34T (fig. 17A) of the bottom portion 34 of the feeder base portion 32 abuts against the carriage stopper 64 of the moving portion 39 from the front (fig. 17A → fig. 17B). The operator senses the contact between the bottom 34 of the feeder base part 32 and the carriage stopper 64 of the moving part 39, and then finishes the insertion of the carriage 21.

While the insertion of the carriage 21 into the base 11 is started until the rear end portion 34T of the bottom portion 34 comes into contact with the moving portion 39, the feeder base portion 32 moves in the horizontal direction (rearward) above the moving portion 39. Further, until the rear end portion 34T of the bottom portion 34 of the feeder base portion 32 comes into contact with the carriage stopper 64 of the moving portion 39, the gate drive pin 153 provided in the feeder base portion 32 comes into contact with the gate drive roller 137 provided in the gate 136 from the front, and presses the entire portion of the gate 136 rearward against the elastic force of the gate spring 145.

The shutter 136 pressed rearward is positioned at the retracted position from the shielding position (fig. 17A → fig. 17B and fig. 18A → fig. 18B). Thereby, the three coupler insertion holes 94 (the first coupler insertion hole 94a, the second coupler insertion hole 94B, and the third coupler insertion hole 94 c) previously covered with the shutter 136, the electrical connector insertion hole 134, and the left and right guide holes 142 are exposed upward (fig. 18B).

As described above, in the present embodiment, when the carriage 21 approaches the base 11, the shutter drive pin 153 provided as a drive member on the feeder base portion 32 of the carriage 21 moves the shutter 136 from the shielding position to the retracted position. Therefore, in a state where the carriage 21 is separated from the base 11, one of the couplers (three coupler sockets 94 as the base-side couplers) covered by the shutter 136, the other of the electrical connectors (the electrical connector sockets 134), and the left and right guide holes 142 are exposed upward.

In a state where rear end portion 34T of feeder base portion 32 abuts trolley stopper 64 of moving portion 39, three connector plugs 95 on the trolley 21 side are positioned above three connector sockets 94 that are exposed when shutter 136 is positioned at the retracted position. The electrical connector plug 152 on the carriage 21 side is positioned above the electrical connector jack 134 (fig. 17A and 19A), and the left and right positioning pins 154 on the carriage 21 side are positioned above the left and right guide holes 142 (fig. 19A). The four engaging pin insertion holes 151 provided in the front, rear, left, and right of the bottom portion 34 of the feeder base portion 32 are located above the four engaging pins 122 provided in the front, rear, left, and right of the moving portion 39 (fig. 17A).

Fig. 23 is a side view showing the component mounting unit 1A and the component supply unit 1B of the component mounting device 1 according to the embodiment of the present invention. After the insertion of the carriage 21 is completed by the bottom portion 34 of the feeder base portion 32 coming into contact with the carriage stopper 64 of the moving portion 39, the operator performs a predetermined operation from an unillustrated operation portion and operates the valve device VL by the control portion 11 CT. Thus, the power air from the power air supply unit DA is supplied to the left and right rod cylinders 83 through the fourth base-side pipe 106, and the left and right rod cylinders 83 are operated to retract the operation rod 83R (fig. 22 → fig. 23).

Thereby, the lever driving cylinder 83 retracts the operating lever 83R, and the driving lever 85 swings in the pivot tip raising direction. Then, the driven roller 77 engaged with the distal end portion of the drive lever 85 is raised, and the moving portion 39 is lifted by the drive lever 85 (fig. 22 → fig. 23). Then, the operating rod 83R of the rod driving cylinder 83 is retracted to the maximum, and the driving rod 85 is in a posture in which the tip thereof is lifted to the maximum, and at this time, the moving portion 39 is held at the second position (fig. 23 and 13B). When the moving portion 39 moves from the first position to the second position in this manner, the lower end portion of the tape discharge guide 37 of the feeder base portion 32 is accommodated in the upper end portion of the carrier tape introduction port 59 provided in the moving portion 39 lifted up by the drive lever 85 (fig. 22 → fig. 23).

When positioned at the second position, the moving unit 39 moves the rear upper roller 70a to the upper surface KZ1 of the rear reference piece 73 and moves the front roller 70c to the upper surface KZ3 of the front reference piece 74. Thereby, the rear upper roller 70a is supported from below by the upper surface KZ1, and the front roller 70c is supported from below by the upper surface KZ 1. Therefore, the moving part 39 is positioned in the Z direction with respect to the guide plate 11P. Further, the moving section 39 brings the rear upper roller 70a into contact with the vertical surface KY1 in the rear upper guide groove 71 from the front in the state of being located at the second position. Therefore, the moving part 39 is also positioned in the Y direction with respect to the guide plate 11P. In the present embodiment, the upper surfaces KZ1 and KZ3 serve as Z-direction reference surfaces for positioning the moving portion 39 in the height direction, and the vertical surface KY1 serves as a Y-direction reference surface for positioning in the horizontal direction (direction along the Y axis).

The moving portion 39 supports and lifts the feeder base portion 32 from below in a state where the four support surfaces 121 are brought into contact with the lower surface of the feeder base portion 32 until being lifted by the drive lever 85 and held at the second position. Therefore, the feeder base part 32 is in a state of being positionally aligned in the height direction with respect to the base 11, and the carrier tape cutting device 16 is also in a state of being positionally aligned in the height direction with respect to the feeder base part 32.

Here, as described above, when the four support surfaces 121 of the moving portion 39 lifted by the drive lever 85 abut on the lower surface of the feeder base portion 32, the four engagement pins 122 provided on the four support surfaces 121 engage with the four engagement pin insertion holes 151 provided on the lower surface of the feeder base portion 32 from below. Accordingly, the feeder base part 32 is lifted by the moving part 39 in a state of being positionally aligned with respect to the moving part 39.

That is, in the present embodiment, the support surface 121 not placed on the moving portion 39 has a function of supporting the feeder base portion 32 from below, and the engagement pin 122 provided on the support surface 121 functions as an engagement portion for performing alignment in the horizontal direction of the feeder base portion 32. Further, an engagement pin insertion hole 151 provided in the bottom of the feeder base part 32 serves as an engaged part with which the engagement pin 122 serving as an engagement part is engaged. As described above, the present embodiment has the following configuration: a side plate 43 as a support member is provided at the moving portion 39, the side plate 43 has a support surface 121 that supports the feeder base portion 32 from below and an engaging pin 122 as an engaging portion that performs positional alignment in the horizontal direction of the feeder base portion 32, and an engaging pin insertion hole 151 as an engaged portion that engages with the engaging pin 122 is provided at the bottom portion 34 of the feeder base portion 32.

As described above, in the component mounting device 1 of the present embodiment, the moving unit 39 is provided in a state in which the vertical movement with respect to the base 11 is permitted, and the moving unit driving mechanism 40 moves the moving unit 39 upward in a state in which the carriage 21 is mounted on the base 11. The moving portion 39 lifts and holds the feeder base portion 32 while moving upward, so that the feeder base portion 32 is positionally aligned with respect to the base 11, and the carrier tape cutting device 16 is positionally aligned with respect to the feeder base portion 32. Therefore, the positional alignment of the feeder base part 32 with respect to the base 11 and the positional alignment of the carrier tape cutting device 16 with respect to the feeder base part 32, which are required when the carriage 21 is assembled to the base 11, can be easily performed.

Conventionally, when the carriage 21 is mounted on the base 11, the feeder base part 32 lifted up is lowered to be in contact with the upper surface of the base 11, and the alignment of the feeder base part 32 with respect to the height direction of the base 11 is performed, and therefore, there is a possibility that the component supply unit 22 attached to the feeder base part 32 interferes with the work head 14. However, in the present embodiment, the feeder base part 32 is aligned with respect to the base 11 in the height direction by the operation of lifting the feeder base part 32, and therefore the above possibility does not occur.

Fig. 24A and 24B are cross-sectional side views showing a part of the moving part 39 provided in the component mounting part 1A of the component mounting device 1 according to the embodiment of the present invention together with a part of the feeder base part 32. Further, as described above, the left and right positioning pins 154 protruding downward from the bottom portion 34 of the feeder base portion 32 pass through the left and right guide holes 142 provided in the floating member 133 of the connecting portion 130 from above until the moving portion 39 is lifted by the drive lever 85 and positioned at the second position. Then, three coupler plugs 95 protruding downward from the bottom portion 34 of the feeder base portion 32 are fitted into three coupler sockets 94 provided on the floating member 133 of the connecting portion 130 from above (fig. 19A → 19B and 24A → 24B).

Therefore, the middle portion TB of the first power air transmission pipe DK1 positioned on the bogie 21 side (the portion of the first coupling plug 95a, the relay pipe 92, and the second coupling plug 95 b) is connected to the other portion (the portion on the base 11 side) of the first power air transmission pipe DK 1. As a result, the restriction by the first deactivation mechanism is released, and the carrier tape cutting device 16 can be operated by transmitting the power air to the tool driving cylinder 53 through the first power air transmission pipe DK 1.

Further, substantially at the same time as the three coupler plugs 95 are fitted with the three coupler sockets 94 from above, the electrical connector plug 152 provided at the bottom portion 34 of the feeder base portion 32 is fitted with the electrical connector socket 134 provided at the floating member 133 of the connecting portion 130 from above (fig. 19A → fig. 19B and fig. 24A → fig. 24B). This enables the supply of power and the transmission of signals from the base 11 side to the component supply unit 22 side, and the component supply unit 22 can be operated.

As described above, in the present embodiment, the carriage-side couplers (three coupler plugs 95) of the first power air transmission pipe DK1 and the second power air transmission pipe DK2 are connected to the base-side couplers (three coupler sockets 94) in the process in which the moving portion 39 approaches the bottom portion 34 of the feeder base portion 32. At the same time, a carriage-side connector (electrical connector plug 152) in an electrical system circuit that transmits power and signals to the component supply unit 22 is connected to a base-side connector (electrical connector socket 134).

As described above, the floating member 133 provided with the coupler socket 94 and the electrical connector socket 134 is elastically supported by the plurality of spring members 139 to be in a floating state. Therefore, even if the axes of the coupling plug 95 and the coupling socket 94 and the axes of the electrical connector plug 152 and the electrical connector socket 134 are slightly deviated from each other, the floating member 133 is sunk due to the compression of the spring member 139, and thus the coupling and the electrical connector are connected under the appropriate pressure, respectively. In addition, the position of the floating member 133 in the horizontal direction is also finely adjusted, so that the coupler and the electrical connector are reliably connected, respectively.

As described above, until the moving portion 39 is lifted by the drive lever 85 and positioned at the second position, the safety stopper 11T positioned at the previous blocking position is disengaged from the stopper insertion hole 44H, and therefore the movement restriction of the moving blade 52 by the second invalidation mechanism is released. Further, since the movable safety cover 111 is moved from the protection position covering the fixed blade edge 51E to the exposure position exposing the fixed blade edge 51E, the cutter 50 is in a usable state.

Next, a case where the carriage 21 is separated from the base 11 will be described. In order to separate the carriage 21 from the base 11, the operator operates the valve device VL from the operation unit, not shown, to operate the left and right rod cylinders 83, and after the operation rod 83R has advanced to the maximum extent, the carriage 21 is extracted from the base 11.

While the moving portion 39 moves from the second position to the first position (fig. 23 → 22) until the operating levers 83R of the left and right lever-drive cylinders 83 are in a state of being advanced to the maximum extent, the four support surfaces 121 of the moving portion 39 are separated downward from the lower surface of the feeder base portion 32 during this time, and the state in which the feeder base portion 32 is lifted up by the moving portion 39 is released. Further, since the carriage-side coupling and the base-side coupling are separated from each other (fig. 19B → 19A and fig. 20B → 20A) until the moving portion 39 moves from the second position to the first position, the tool driving cylinder 53 becomes inoperable (first deactivation mechanism). Since the safety stopper 11T is inserted into the stopper insertion hole 44H and positioned at the stopping position (fig. 13B → 13A), the cutter 50 is in a state in which the movement of the movable blade 52 toward the fixed blade 51 is stopped (second invalidation mechanism).

As described above, in the component mounting device 1 of the present embodiment, since the carrier tape cutting device 16 (the cutter 50) is disabled by the invalidation mechanism (the first invalidation mechanism, the second invalidation mechanism) in the state where the carriage 21 is separated from the base 11, the operation of cutting the carrier tape CT is disabled, even when the cutter 50 of the carrier tape cutting device 16 is located within the reach of the hand of the operator in the state where the carriage 21 is separated from the base 11, the safety of the operator can be ensured.

Further, in the process of the movement of the moving portion 39 from the second position to the first position, the movable safety cover 111 is moved from the exposed position to the protection position (fig. 13A → 13A), and the fixed blade edge 51E is protected by the movable safety cover 111. As described above, in the component mounting device 1 of the present embodiment, since the movable safety cover 111 covers and protects the edge (fixed blade edge 51E) of the cutter 50 of the tape cutting device 16 in the state where the carriage 21 is separated from the base 11, the safety of the operator can be ensured even when the cutter 50 of the tape cutting device 16 is positioned within the reach of the hand of the operator in the state where the carriage 21 is separated from the base 11.

When the operating rod 83R of the rod cylinder 83 is in a state of being advanced to the maximum extent, the moving portion 39 is located at the first position, and the carriage 21 is drawn out forward of the base 11 (fig. 22 → fig. 21), the shutter drive pin 153 provided in the feeder base portion 32 moves forward, whereby the shutter 136 is returned to the shielding position by the elastic force of the shutter spring 145 (fig. 18B → fig. 18A). Accordingly, the three coupling plugs 95, the electrical connector socket 134, and the left and right guide holes 142 are covered with the shutter 136 (fig. 17A and 18B), and therefore, dust and dirt are prevented from entering the openings of the three upward-facing coupling sockets 94 and the electrical connector socket 134. In the operation of loading and unloading the carriage 21 to and from the base 11, there is a possibility that the component is scattered from the carrier tape CT by vibration and falls into the connection portion 130, but even in such a case, the component does not enter the upward facing coupler or connector.

As described above, in the component mounting device 1 of the present embodiment, the base-side coupler (three coupler sockets 94) connected to the carriage-side coupler (three coupler plugs 95) in the state where the carriage 21 is attached to the base 11, and the base-side connector (electrical connector socket 134) connected to the carriage-side connector (electrical connector plug 152) are covered with the shutter 136 in the state where the carriage 21 is separated from the base 11. Therefore, it is possible to prevent dust and dirt from entering the respective openings of the upward-facing base-side coupler (three coupler sockets 94) and the base-side connector (electric connector socket 134), and to prevent various failures that may occur due to dust and dirt entering these openings. Further, since the intrusion of the dust or dirt into the opening is prevented, the dust or dirt removing work required when the dust or dirt intrudes into the opening is not required.

As described above, in the component mounting device 1 of the present embodiment, since the carrier tape cutting device 16 (the cutter 50) is disabled by the invalidation mechanism (the first invalidation mechanism, the second invalidation mechanism) in the state where the carriage 21 is separated from the base 11, the safety of the operator can be ensured even when the carriage 21 is separated from the base 11 and the cutter 50 of the carrier tape cutting device 16 is located within the reach of the hand of the operator.
